Prevalence of qnr Genes in Extended-Spectrum β-Lactamase Producing Klebsiella pneumoniae Isolated from Clinical Urine Specimens in University Teaching Hospitals, Iran
Background and Aims: Extended-spectrum β-lactamase (ESBL) producing gram negative bacteria are resistant to penicillins, narrow and extended-spectrum cephalosporins, and aztreonam; also they are frequently resistant to trimethoprim-sulfamethoxazole, aminoglycosides, and quinolones. This study aimed to investigate the prevalence of plasmid-mediated quinolone resistance (PMQR) determinants q...
متن کاملClonal Dissemination of Extended-Spectrum β-Lactamase (ESBL)-Producing Klebsiella pneumoniae Isolates in a Korean Hospital
In this study, we investigated the molecular characteristics of extended-spectrum beta-lactamase (ESBL)-producing Klebsiella pneumoniae isolates that were recovered from an outbreak in a Korean hospital. A new multilocus sequence typing (MLST) scheme for K. pneumoniae based on five housekeeping genes was developed and was evaluated for 43 ESBL-producing isolates from an outbreak as well as 38 s...
متن کاملPrevalence of extended spectrum β-lactamase (ESBL) producing E. coli and Klebsiella species in urinary isolates
Introduction: Bacterial resistance to β-lactam antibiotics has risen dramatically, with extended spectrum βlactamase (ESBL) contributing to this increase. Early identification of ESBL production is becoming increasingly important. Methodology: A total of 367 consecutive, urine samples from patients suspected to have UTI, were processed. All Escherichia coli and Klebsiella species isolated in si...
متن کاملHigh Prevalence of CTXM-15 Type Extended-Spectrum Beta-Lactamase Among Clinical Isolates of Klebsiella Pneumoniae
Background: Production of β–lactamases by enterobacteriacea, especially Klebsiella pneumoniae, is one of the emerging health problems in the world. The purpose of this study was to assess the frequency of blaCTX-M15 gene in K. pneumoniae isolates and determine the molecular diversity of CTXM producing isolates. Methods: In...
متن کاملPrevalence of Plasmid-Mediated Quinolone Resistance Genes among Extended-Spectrum β-Lactamase-Producing Klebsiella pneumoniae Human Isolates in Iran
The purpose of this study was to determine the prevalence and molecular characterization of plasmid-mediated quinolone resistance (PMQR) genes (qnrA, qnrB, qnrS, aac(6')-Ib-cr, and qepA) among ESBL-producing Klebsiella pneumoniae isolates in Kashan, Iran. A total of 185 K. pneumoniae isolates were tested for quinolone resistance and ESBL-producing using the disk diffusion method and double disk...
